What is Dry Ice Blasting?

Dry ice blasting uses compressed air to propel dry ice pellets onto a contaminated surface. It removes dirt and coatings through three effects working together:

1. Impact

   The high-speed pellets strike the surface, cracking and loosening the contamination. This mechanical action begins to break up the unwanted layer and allows the cleaning process to reach beneath it.

2. Thermal shock

   At approximately −78°C, the pellets rapidly cool the contamination, making it brittle and weakening its bond with the surface underneath. Cracks form in the unwanted layer, making it easier to remove.

3. Sublimation

   On contact, the dry ice changes directly from a solid into a gas. The rapid expansion helps lift the loosened contamination away from the surface. The dry ice itself disappears, leaving no spent blasting media behind.

Together, these effects provide a dry, non-abrasive cleaning process without added water or chemical cleaning agents. With no secondary blasting-media waste, cleanup focuses on the contamination removed.
